在隧道建设的桥梁方案、桥隧结合方案、全隧道方案等既有方案各有利弊、选择难以定夺的困惑下,提出一个进一步优化的“蛙泳式”的设计方案,将最大限度地集成各方案的优点、规避其弊端,使通道项目既充分利用了渤海口的各种有利条件,又能够最大限度地保护环境、降低成本、提高安全性。该方案将为项目的可行性提供又一坚实证据,对决策者最终下定“开建”决心具有重要参考价值。

Based on the strength and weakness of bridge scheme, bridge-tunnel scheme and tunnel scheme,an optimized construction scheme named breaststroke type is put forward. Integrating advantages of other schemes and avoiding their disadvantages, the scheme not only makes full use of various advantage conditions of Bohai, but also protects environment, reduces cost and enhances safety farthest. It provides a solid evidence to the feasibility of tunnel project and has important reference value for decision maker’s construction decision.
